Greedy Or Not

One evening when the mother was fetching her daughter home from her work place... on the way they stopped at the Railway station for super.....

hmmmm after having a bowl of mee soto (noodles in chicken soup with spices) they decided to the walk back to the car...

As they drove off sudden... the sound of poooot...

Daughter: why do you have to trap me here.....
Mom: Oh i trap you here but.... but i didnt tie your hands
(as the mother unwind the wind to let in some polluted air from the street.....
Mom: Oooooi didnt i wind down you window?
Daughter: I wind it back up..because i remember there are air refreshner here
Mom: So was the pooooot that smelly?
Daughter: I didnt smell it.....
Mom: Oh that mean you are not so greedy
Daughter: Huh
Mom: Well that pooot is the air and the air is free..... you didnt inhale all the air from the pooooot....so you are not greedy in taking other,s exhausted air....
so therefore you are not too greedy my dear girl.... I am glad.,
